PROBLEM TO BE SOLVED: To provide a method of manufacture of elastic crawler manufacturing some elastic crawlers having different circumferential lengths at a low cost. SOLUTION: This method of manufacture of an elastic crawler 1 is carried out such that a non-vulcanized endless belt-like pre-molded product 1A is integrally molded and vulcanized among a plurality of molds 31. The mold 31 is constituted in an endless manner by a pair of parallel straight lines 32c, 33c and a pair of arcuate portions 32d, 33d of which circumferential ends are abutted against both ends of the straight lines 32c, 33c. Lengths of the straight lines 32c, 33c are replaced to each other in compliance with a circumferential length of the elastic crawler 1 to be manufactured. COPYRIGHT: (C)2005,JPO&NCIPI |
